Top 10 enriched gene ontology terms among potential excretory–secretory protein (ESP) transcripts from advanced third-stage larvae of Gnathostoma spinigerum (aL3Gs). Classical (left) and non-classical ESPs (right) were categorized into three gene ontology classifications: molecular functions (upper), cellular components (middle), and biological processes (lower). Gene ontology functions are shown on the left Y-axis. The number of transcripts is shown on the right Y-axis.
